ABSTRACT

A cannabis processing system comprises a grinding apparatus and a cell disruption apparatus. The grinding apparatus is configured to grind wet cannabis cuttings to from a ground, wet cannabis material comprising wet cannabis particles having an average particle size within a range of from about 1 mm to about 3 mm. The cell disruption apparatus is downstream of the grinding apparatus and is configured to disrupt cell walls of plant cells of the wet cannabis particles through one or more of flash freezing, a cellulose solvent, applied negative pressure, and vacuum distillation to facilitate removal of one or more cannabinoids within the plant cells of the wet cannabis particles. Methods of processing cannabis are also described.

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Patent Application Ser. No. 62/837,613, filed Apr. 23, 2019, the disclosure of which is hereby incorporated herein in its entirety by this reference.

TECHNICAL FIELD

The disclosure, in various embodiments, relates to cannabis processing systems and methods. More specifically, embodiments of the disclosure relate to cannabis processing systems and methods employing disruption of cell walls of wet cannabis particles through one or more of flash freezing, cellulose solvent exposure, applied negative pressure, and vacuum distillation.

BACKGROUND

Cannabis is a genus of plants in the family Cannabaceae. Acknowledged Cannabis species include Cannabis sativa, Cannabis indica and Cannabis ruderalis. Cannabis plants include numerous (400+) cannabinoids (C₂₁ terpenophenolic compounds), some of which can provide therapeutic and medicinal benefits. For example, different cannabinoids have been utilized to treat various conditions, such as pain, nausea, seizures, convulsions, vomiting, lack of appetite, inflammation, psychosis, arthritis, cancer, and other conditions. In addition, different cannabinoids have been used to provide various desired effects, such as psychoactive effects, neuroprotective effects, and immunomodulatory effects. To date, eighty-five (85) cannabinoids have been isolated from cannabis plants.

Unfortunately, conventional systems and methods of processing cannabis to obtain desirable cannabinoids therefrom suffer from a variety of disadvantages. For example, one conventional method of processing cannabis to obtain desirable cannabinoids therefrom includes drying harvested, wet portions of cannabis plants to a moisture content of less than fifteen (15) percent, shredding the dried portions of the cannabis plants to form dry cannabis particles (e.g., a powder of dry cannabis particles), and then extracting desired cannabinoids from the dry cannabis particles using an extraction agent (e.g., an extraction solvent). Drying the harvested portions of the cannabis plants ruptures cell walls of the plant cells thereof to permit the extraction of cannabinoids within the plant cells using the extraction agent. However, the drying process can be undesirably long (e.g., weeks) and/or require costly and energy-intensive equipment (e.g., heating apparatuses) and personnel to expedite the process. In addition, other conventional methods of processing cannabis that forego the drying process and treat harvested, wet portions of cannabis plants with an extraction agent generally have undesirably low cannabinoid product yields, such as less than or equal to about 50 percent.

Accordingly, there is a need for new cannabis processing systems and methods that are fundamentally different than conventional technologies.

An embodiment of the disclosure will now be described with reference to FIG. 1, which schematically illustrates a cannabis processing system 100. The cannabis processing system 100 may be used to process wet cannabis cuttings to access and extract one or more cannabinoids contained within plant cells thereof, which may then be removed (e.g., separated) from other chemical compounds (e.g., non-cannabinoid compounds, such as esters, terpenes, water; other cannabinoids) of the wet cannabis cuttings. As a non-limiting example, the cannabis processing system 100 may be used to access and extract, from the plant cells of the wet cannabis cuttings, one or more of tetrahydrocannabinol (THC), delta-8-THC, tetrahydrocannabinolic acid (THCA), tetrahydrocannabivarin (THCV), tetrahydrocannabivarinic acid (THCVA), cannabidiol (CBD), cannabidiolic acid (CBDA), cannabidivarin (CBDV), cannabidivarinic acid (CBDVA), cannabinol (CBN), cannabinolic acid (CBNA), cannabavarin (CBV), cannabavarinic acid (CBVA), cannabigerol (CBG), cannabigerolic acid (CBGA), cannabigerovarin (CBGV), cannabigerovarinic acid (CBGVA), cannabinidiol (CBND), cannabinidiolic acid (CBNDA), cannabichromene (CBC), cannabichromenic acid (CBCA), cannabichromevarin (CBCV), cannabichromevarinic acid (CBCVA), cannabicyclol (CBL), cannabicyclolic acid (CBLA), cannabitriol (CBT), cannabitriolic acid (CBTA), cannabielsoin (CBE), and cannabielsoinic acid (CBEA), and cannabigerol monomethyl ether (CBGM). As used herein, THC, THCV, CBD, CBDV, CBN, CBV, CBG, CBGV, CBND, CBC, CBCV, CBL, CBT, CBE, and CBGM refer to the decarboxylated form of the cannabinoid; and THCA, THCVA, CBDA, CBNA, CBVA, CBGA, CBGVA, CBNDA, CBCA, CBCVA, CBLA, CBTA, and CBEA refer to the acid form of the cannabinoid. As another non-limiting example, the cannabis processing system 100 may be used to access and extract, from the plant cells of the wet cannabis cuttings, one or more terpenes.

As used herein, “wet cannabis cuttings” means and includes harvested portions (e.g. cuttings, trimmings, pickings, pluckings) of one or more cannabis plants including at least about fifteen (15) percent of the water present within the harvested portions at the time of harvesting. The wet cannabis cuttings may include one or more of buds, flowers, leaves, stems, and trichomes of the cannabis plants. The wet cannabis cuttings may include greater than or equal to about 15 percent of the water present in the harvested portions of the cannabis plants at the time of harvesting, such as greater than or equal to about 25 percent of the water, greater than or equal to about 50 percent of the water, greater than or equal to about 75 percent of the water, greater than or equal to about 85 percent of the water, greater than or equal to about 95 percent of the water, or even about 100 percent of the water. In some embodiments, the wet cannabis cuttings include a majority (e.g., greater than 50 percent) of the water present in the harvested portions of the cannabis plants at the time of harvesting.

As shown in FIG. 1, the cannabis processing system 100 may include at least one grinding apparatus 102 and at least one cell disruption apparatus 104 downstream of the grinding apparatus 102. Optionally, as described in further detail below, the cannabis processing system 100 may also include one or more of a mechanical dewatering apparatus 106 downstream of the grinding apparatus 102 and upstream of the cell disruption apparatus 104; a wetting apparatus 108 downstream of the mechanical dewatering apparatus 106 and/or the grinding apparatus 102 and upstream of the cell disruption apparatus 104; and a separation apparatus 110 downstream of the cell disruption apparatus 104.

The grinding apparatus 102 may comprise at least one apparatus configured and operated to receive a wet cannabis feed 112 including wet cannabis cuttings and to mechanically break down (e.g., grind, shred, chip, rend) the wet cannabis cuttings to form a ground, wet cannabis material 114 including relatively smaller, discrete wet cannabis particles (e.g., segments, pieces, parts) having a predetermined average particle size suitable for subsequent operations (e.g., cell disruption operations, cannabinoid extraction operations) of the cannabis processing system 100. The predetermined average particle size of the discrete wet cannabis particles may be large enough to limit release (e.g., liberation) of desirable cannabinoids into intercellular liquid (e.g., intercellular water) of the ground, wet cannabis material 114, and small enough to facilitate desirable interactions between one or more solvents (e.g., cannabinoid extraction solvents; other solvents, such as cellulose solvent) and cannabis plant cells. By way of non-limiting example, the grinding apparatus 102 may be configured and operated to mechanically break down the wet cannabis cuttings of the wet cannabis feed 112 into discrete wet cannabis particles having an average particle size within a range of from about 0.5 millimeter (mm) to about 5 mm, such as from about 1 mm to about 3 mm. Particle sizes of wet cannabis particles may be determined by conventional processes, such as conventional laser diffraction processes and conventional wet sieving processes. For example, particle sizes of wet cannabis particles may be determined using a conventional wet sieving process employing mesh numbers 3½ through 40. In some embodiments, the grinding apparatus 102 is configured to grind (e.g., shred, rend) wet cannabis cuttings of the wet cannabis feed 112 into discrete wet cannabis particles each individually exhibiting a size within a range of from about 1 mm to about 3 mm, as determined by a wet sieving process employing mesh numbers 6 through 20.

The grinding apparatus 102 may exhibit any configuration capable of mechanically breaking down the wet cannabis cuttings into wet cannabis particles having desired sizes (e.g., sizes within a range of from about 1 mm to about 3 mm). By way of non-limiting example, the grinding apparatus 102 may comprise one or more of a grinding roller (e.g., a low speed, high-torque grinding roller, such as a low speed, high-torque dual shafted grinder), a disc chipper, a drum chipper, a tub grinder, a ball mill, and a hammer mill. The grinding apparatus 102 may, optionally, include one or more structures (e.g., screens) configured with an appropriate mesh or other aperture sizing and positioned to ensure that wet cannabis particles exiting the grinding apparatus 102 are within a predetermined particle size range (e.g., within a range of from about 1 mm to about 3 mm).

Although the cannabis processing system 100 is depicted as including a single (e.g., only one) grinding apparatus 102 in FIG. 1, the cannabis processing system 100 may include any number of grinding apparatuses 102. The number of grinding apparatuses 102 included in the cannabis processing system 100 may at least partially depend on a desired output of material(s) for further processing (including recovery of spent (fully extracted) material(s) for use in extracting or producing materials from waste streams). Put another way, the cannabis processing system 100 may include a single (e.g., only one) grinding apparatus 102, or may include multiple (e.g., more than one) grinding apparatuses 102. If the cannabis processing system 100 includes multiple grinding apparatuses 102, each of the grinding apparatuses 102 may be substantially the same (e.g., exhibit substantially the same components, component sizes, component shapes, component material compositions, component material distributions, component positions, component orientations, etc.) and may be operated under substantially the same conditions (e.g., feed rates, grinder speed, grinder torque, etc.), or at least one of the grinding apparatuses 102 may be different (e.g., exhibit one or more of different components, different component sizes, different component shapes, different component material compositions, different component material distributions, different component positions, different component orientations, etc.) than at least one other of the grinding apparatuses 102 and/or may be operated under different conditions (e.g., a different feed rate, a different grinder speed, a different grinder torque, etc.) than at least one other of the grinding apparatuses 102. In some embodiments, two of more grinding apparatuses 102 are provided in parallel with one another. In additional embodiments, two of more grinding apparatuses 102 are provided in series with one another.

With continued reference to FIG. 1, if present, the mechanical dewatering apparatus 106 may comprise at least one apparatus configured and operated to receive and partially (e.g., less than completely) mechanically remove excess water from the ground, wet cannabis material 114 exiting the grinding apparatus 102 to form a partially dewatered cannabis material 116. The mechanical dewatering apparatus 106 may be configured and operated to substantially remove intercellular water of the ground, wet cannabis material 114 while substantially maintaining intracellular water of the ground, wet cannabis material 114. In some embodiments, the mechanical dewatering apparatus 106 is configured and operated to remove from about 75 percent to about 95 percent of intercellular water present within the ground, wet cannabis material 114, such as from about 80 percent to about 90 percent of the intercellular water present within the ground, wet cannabis material 114. The water content of the ground, wet cannabis material 114 and the partially dewatered cannabis material 116 may be determined using conventional moisture measurement processes and equipment, such as one or more conventional volumetric moisture sensors.

The mechanical dewatering apparatus 106, if any, may exhibit any configuration capable of partially mechanically dewatering the ground, wet cannabis material 114. By way of non-limiting example, the grinding apparatus 102 may comprise one or more of a pressing apparatus (e.g., a roller press, such as a cold roller press), a filtration apparatus (e.g., a vacuum filtration apparatus), and a centrifuge apparatus. In some embodiments, the mechanical dewatering apparatus 106 is a roller press. The roller press may, for example, press the ground, wet cannabis material 114 between one or more pairs of rollers to partially dewater and reduce a thickness of the ground, wet cannabis material 114. The roller press may produce one or more sheet structures comprising a partially dewatered cannabis material including the discrete wet cannabis particles of the ground, wet cannabis material 114. In additional embodiments, the mechanical dewatering apparatus 106 is a vacuum filtration apparatus configured and operated to apply negative pressure to the ground, wet cannabis material 114 to remove intercellular water of the ground, wet cannabis material 114 and form the partially dewatered cannabis material 116.

The cannabis processing system 100 may include any number of mechanical dewatering apparatuses 106, such as a single (e.g., only one) mechanical dewatering apparatus 106, multiple (e.g., more than one) mechanical dewatering apparatuses 106, or no mechanical dewatering apparatuses 106. If the cannabis processing system 100 includes multiple mechanical dewatering apparatuses 106, each of the mechanical dewatering apparatuses 106 may be substantially the same and may be operated under substantially the same conditions, or at least one of the mechanical dewatering apparatuses 106 may be different than at least one other of the mechanical dewatering apparatuses 106 and/or may be operated under different conditions than at least one other of the mechanical dewatering apparatuses 106. In some embodiments, two of more mechanical dewatering apparatuses 106 are provided in parallel with one another. In additional embodiments, two of more mechanical dewatering apparatuses 106 are provided in series with one another.

With continued reference to FIG. 1, if present, the wetting apparatus 108 may comprise at least one apparatus configured and operated to wet the partially dewatered cannabis material 116 exiting the mechanical dewatering apparatus 106 (if any) (or the ground, wet cannabis material 114 exiting the grinding apparatus 102) with at least one cannabinoid extraction solvent (e.g., a cannabinoid extraction solvent to be employed in a subsequent extraction step) to form a wetted cannabis material 118. The cannabinoid extraction solvent may, for example, comprise one or more of acetone, acetonitrile, butane, 1-butanol, 2-butanol, dichloromethane, diethyl ether, ethanol, ethyl acetate, hexane, heptane, isopropyl acetate, methanol, isopropanol, isopropyl ether, and methyl tert-butyl ether. In some embodiments, the cannabinoid extraction solvent is ethanol. The wetting apparatus 108 may be configured and operated to add enough cannabinoid extraction solvent to the partially dewatered cannabis material 116 to facilitate a weight ratio of solids to liquids within the wetted cannabis material 118 within a range of from about 2:1 to about 5:1.

The wetting apparatus 108, if any, may exhibit any configuration capable of wetting the partially dewatered cannabis material 116 (or the ground, wet cannabis material 114) with the cannabinoid extraction solvent. By way of non-limiting example, the wetting apparatus 108 may comprise a spray chamber apparatus configured to receive the partially dewatered cannabis material 116 and the cannabinoid extraction solvent, and to form and direct (e.g., spray) discrete portions (e.g., drops, aerosol) of the cannabinoid extraction solvent onto to the partially dewatered cannabis material 116.

In some embodiments, the wetting apparatus 108, if any, is configured and operated to add cooled cannabinoid extraction solvent to the partially dewatered cannabis material 116. The cannabinoid extraction solvent may, for example, be cooled (e.g., supercooled) to a temperature near the freezing temperature of the cannabinoid extraction solvent. By way of non-limiting example, the cannabinoid extraction solvent may be cooled to a temperature within 20° C. (e.g., within 10° C., within 5° C., within 2.5° C., or within 1° C.) of the freezing temperature of the cannabinoid extraction solvent. Wetting the partially dewatered cannabis material 116 with a cooled (e.g., supercooled) cannabinoid extraction solvent may enhance thermal transfer properties of the wetted cannabis material 118 relative to the partially dewatered cannabis material 116 to enhance the efficiency of subsequent cell disruption operations (e.g., flash freezing operations, if employed) using the cell disruption apparatus 104, as described in further detail below. The cannabinoid extraction solvent may be cooled within the wetting apparatus 108 and/or may be cooled outside of the wetting apparatus 108 (e.g., using one or more heat transfer apparatuses) and delivered to the wetting apparatus 108.

The cannabis processing system 100 may include any number of wetting apparatuses 108, such as a single (e.g., only one) wetting apparatus 108, multiple (e.g., more than one) wetting apparatuses 108, or no wetting apparatuses 108. If the cannabis processing system 100 includes multiple wetting apparatuses 108, each of the wetting apparatuses 108 may be substantially the same and may be operated under substantially the same conditions, or at least one of the wetting apparatuses 108 may be different than at least one other of the wetting apparatuses 108 and/or may be operated under different conditions than at least one other of the wetting apparatuses 108. In some embodiments, two of more wetting apparatuses 108 are provided in parallel with one another. In additional embodiments, two of more wetting apparatuses 108 are provided in series with one another.

With continued reference to FIG. 1, the cell disruption apparatus 104 comprises at least one apparatus configured and operated to at a least partially (e.g., substantially) disrupt (e.g., break down) cell walls of plant cells of the wet cannabis particles produced by the grinding apparatus 102. Disrupting the cell walls of the plant cells of the wet cannabis particles may facilitate the access to one or more cannabinoids within the plants cells, such as cannabinoids attached to intracellular surfaces of the plant cells, to permit removal (e.g., extraction) of the cannabinoids using one or more additional processing acts (e.g., one or more cannabinoid extraction acts). Disrupting the cell walls of the plant cells of the wet cannabis particles may also directly effectuate the release (e.g., liberation, detachment) of one or more cannabinoids from surfaces (e.g., intracellular surfaces, intercellular surfaces) the plant cells, such as inner surfaces and/or outer surfaces of the cell walls of the plant cells.

As shown in FIG. 1, the cell disruption apparatus 104 may receive the ground, wet cannabis material 114 from the grinding apparatus 102, the partially dewatered cannabis material 116 from the mechanical dewatering apparatus 106 (if any), or the wetted cannabis material 118 from the wetting apparatus 108 (if any), and may disrupt the cell walls of plant cells of the wet cannabis particles thereof to produce a cellularly-disrupted cannabis effluent 120. As described in further detail below, the cell disruption apparatus 104 may be configured and operated to subject the wet cannabis particles to one or more of flash freezing, contact with at least one cellulose solvent, and one or more applied negative pressures to disrupt the cell walls of the plant cells thereof.

In some embodiments, the cell disruption apparatus 104 comprises an apparatus configured and operated to subject the wet cannabis particles produced by the grinding apparatus 102 to flash freezing to disrupt the cell walls of the plant cells of the wet cannabis particles. The cell disruption apparatus 104 may, for example, be configured and operated to cool (e.g., rapidly cool) the wet cannabis particles to a crystallization temperature sufficient to crystallize and expand intracellular fluid (e.g., intracellular water) of the plant cells, and then maintain the crystallization temperature until the intracellular fluid is substantially crystallized. The crystallization and expansion of the intracellular fluid of the plant cells may rupture the cell walls of the plant cells to facilitate access to cannabinoids contained within the intracellular space (e.g., on intracellular surfaces) of the plant cells. The cell disruption apparatus 104 may receive and cool the ground, wet cannabis material 114, the partially dewatered cannabis material 116 (if produced using the mechanical dewatering apparatus 106), or the wetted cannabis material 118 (if produced using the wetting apparatus 108) to flash freeze the wet cannabis particles produced by the grinding apparatus 102. In some embodiments, the cell disruption apparatus 104 receives and acts upon the wetted cannabis material 118 from the grinding apparatus 102 (e.g., the mechanical dewatering apparatus 106 and the wetting apparatus 108, along with the processing acts associated therewith, are employed upstream of the cell disruption apparatus 104). The wetted cannabis material 118 (or the ground, wet cannabis material 114; or the partially dewatered cannabis material 116) may, for example, comprise greater than or equal to about fifty (50) percent of the water present, at the time of harvesting, within the harvested portions of one or more cannabis plants employed to form the wetted cannabis material 118.

The parameters (e.g., crystallization temperature, cooling rate, cooling duration, cooling media) employed by the cell disruption apparatus 104 (e.g., flash freezing apparatus) to flash freeze the wet cannabis particles may at least partially depend on the thermal mass of the material (e.g., the ground, wet cannabis material 114, the partially dewatered cannabis material 116, or the wetted cannabis material 118) being received and acted upon by the cell disruption apparatus 104. The crystallization temperature, the cooling rate to reach to the crystallization temperature, and the period of time the crystallization temperature may be selected to promote expansion (and, hence, impede shrinking) of the intracellular fluid through the flash freezing process. In some embodiments, the crystallization temperature, the cooling rate to reach to the crystallization temperature, and the period of time that the crystallization temperature is maintained are selected to maximize the volume of crystalline material formed from the intracellular fluid through the flash freezing process. As a non-limiting example, in some embodiments (e.g., embodiments wherein the cell disruption apparatus 104 receives and acts upon the wetted cannabis material 118) the crystallization temperature is selected to be within a range of from about −60° C. to about −80° C. (e.g., from about −70° C. to about −80° C.), the crystallization temperature is reached (e.g., starting from room temperature, such as from about 20° C. to about 22° C.) in less than or equal to about two (2) minutes (e.g., less than or equal to about one (1) minute, less than or equal to about 45 seconds, less than or equal to about 30 seconds, less than or equal to about 15 seconds), and the crystallization temperature is maintained for a period of time within a range of from about one (1) minute to about ten (10) minutes (e.g., from about one (1) minute to about five (5) minutes, from about one (1) minute to about three (3) minutes). In some embodiments, at least one cannabinoid extraction solvent (e.g., one or more of acetone, acetonitrile, butane, 1-butanol, 2-butanol, dichloromethane, diethyl ether, ethanol, ethyl acetate, hexane, heptane, isopropyl acetate, methanol, isopropanol, isopropyl ether, and methyl tert-butyl ether) cooled to the crystallization temperature is employed as a cooling media for the flash freezing process. The cannabinoid extraction solvent may, for example, be combined (e.g., mixed) with the wet cannabis particles within the cell disruption apparatus 104. In further embodiments, a different cooling media (e.g., a cooling media other than a cannabinoid extraction solvent) is employed as a cooling media for the flash freezing process.

In additional embodiments, the cell disruption apparatus 104 comprises an apparatus configured and operated to treat the wet cannabis particles produced by the grinding apparatus 102 with at least one cellulose solvent to disrupt the cell walls of the plant cells of the wet cannabis particles. The cell disruption apparatus 104 may, for example, be configured and operated to contact (e.g., spray, coat, immerse) the wet cannabis particles with the cellulose solvent for a sufficient period of time to dissolve cellulose of the cell walls of the plant cells of the wet cannabis particles. Dissolving the cellulose of the cell walls may facilitate access to cannabinoids contained within the intracellular space (e.g., on intracellular surfaces) of the plant cells. Dissolving the cellulose of the cell walls may also free (e.g., liberate, detach, unbind) cannabinoids attached to and/or contained within the cell walls, such as cannabinoids attached to surfaces (e.g., inner surfaces, outer surfaces) of the cell walls. The cell disruption apparatus 104 may receive and treat the ground, wet cannabis material 114, the partially dewatered cannabis material 116 (if produced using the mechanical dewatering apparatus 106), or the wetted cannabis material 118 (if produced using the wetting apparatus 108) with the cellulose solvent to disrupt the cell walls of the plant cells of the wet cannabis particles produced by the grinding apparatus 102. In some embodiments, the cell disruption apparatus 104 receives and treats the ground, wet cannabis material 114 from the grinding apparatus 102 (e.g., the mechanical dewatering apparatus 106 and the wetting apparatus 108, along with the processing acts associated therewith, are not employed upstream of the cell disruption apparatus 104). The ground, wet cannabis material 114 (or the partially dewatered cannabis material 116; or the wetted cannabis material 118) may, for example, comprise greater than or equal to about fifteen (15) percent of the water present, at the time of harvesting, within the harvested portions of one or more cannabis plants employed to form the ground, wet cannabis material 114.

If a cellulose solvent is used to disrupt the cell walls of plant cells of the wet cannabis particles produced by the grinding apparatus 102, the cell disruption apparatus 104 may exhibit any configuration capable of treating the wet cannabis particles with the cellulose solvent. By way of non-limiting example, the cell disruption apparatus 104 may comprise a spray chamber apparatus configured to receive the ground, wet cannabis material 114 (or the partially dewatered cannabis material 116, or the wetted cannabis material 118) and the cellulose solvent, and to form and direct (e.g., spray) discrete portions (e.g., drops, aerosol) of the cellulose solvent onto to the ground, wet cannabis material 114 (or the partially dewatered cannabis material 116, or the wetted cannabis material 118).

The cell disruption apparatus 104 may utilize a cellulose extract solvent (if any) able to dissolve cellulose of the cell walls of the plant cells of the wet cannabis particles without modifying the chemical structures of desirable cannabinoids (e.g., THC, CBD, etc.) of the wet cannabis particles. The cellulose extract solvent may also be selected to be readily separable from the desirable cannabinoids. In addition, the cellulose extract solvent may be selected to be relatively non-hazardous (e.g., non-toxic) and environmentally friendly. By way of non-limiting example, the cellulose extract solvent (if any) may comprise one or more of 4-methylmorpholine 4-oxide (NMMO), an ionic liquid, dimethylsulfoxide (DMSO), paraformaldehyde (PFA), dimethylformamide (DMF), and dimethylacetamide (DMAc). Furthermore, the cellulose extract solvent (if any) may be combined with (e.g., added to) the ground, wet cannabis material 114 (or the partially dewatered cannabis material 116, or the wetted cannabis material 118) under any desirable conditions (e.g., temperatures, pressures) able to maintain the chemical structure(s) of the desirable cannabinoid(s) of the wet cannabis particles.

In further embodiments, the cell disruption apparatus 104 comprises an apparatus configured and operated to apply negative pressure to the wet cannabis particles produced by the grinding apparatus 102 to disrupt the cell walls of the plant cells of the wet cannabis particles. The cell disruption apparatus 104 may, for example, be configured and operated to subject the wet cannabis particles to applied negative pressure within a range of from about −2 pounds per square inch gauge (psig) to about −10 psig. Applying negative pressure to the wet cannabis particles may rupture the cell walls of the plant cells to facilitate access to cannabinoids contained within the intracellular space (e.g., on intracellular surfaces) of the plant cells. The cell disruption apparatus 104 may receive and apply negative pressure to the ground, wet cannabis material 114, the partially dewatered cannabis material 116 (if produced using the mechanical dewatering apparatus 106), or the wetted cannabis material 118 (if produced using the wetting apparatus 108) to act upon the wet cannabis particles produced by the grinding apparatus 102. In some embodiments, the cell disruption apparatus 104 receives and applies negative pressure to the ground, wet cannabis material 114 from the grinding apparatus 102 (e.g., the mechanical dewatering apparatus 106 and the wetting apparatus 108, along with the processing acts associated therewith, are not employed upstream of the cell disruption apparatus 104). The ground, wet cannabis material 114 (or the partially dewatered cannabis material 116; or the wetted cannabis material 118) may, for example, comprise greater than or equal to about twenty-five (25) percent of the water present, at the time of harvesting, within the harvested portions of one or more cannabis plants employed to form the ground, wet cannabis material 114.

In still further embodiments, the cell disruption apparatus 104 comprises an apparatus configured and operated to subject the wet cannabis particles produced by the grinding apparatus 102 to a vacuum distillation process to disrupt the cell walls of the plant cells of the wet cannabis particles. Subjecting the wet cannabis particles to the vacuum distillation process may rupture the cell walls of the plant cells to facilitate access to cannabinoids contained within the intracellular space (e.g., on intracellular surfaces) of the plant cells. The vacuum distillation process may also separate different chemical compounds (e.g., different non-cannabinoid compounds, such as terpenes, esters, water, etc.; different cannabinoid compounds, such as CBD, THC; etc.) of the wet cannabis particles from one another based on differences in the volatilities thereof, as described in further detail below. The cell disruption apparatus 104 may receive and act upon the ground, wet cannabis material 114, the partially dewatered cannabis material 116 (if produced using the mechanical dewatering apparatus 106), or the wetted cannabis material 118 (if produced using the wetting apparatus 108) to subject the wet cannabis particles produced by the grinding apparatus 102 to vacuum distillation. In some embodiments, the cell disruption apparatus 104 receives and subjects the ground, wet cannabis material 114 from the grinding apparatus 102 to vacuum distillation (e.g., the mechanical dewatering apparatus 106 and the wetting apparatus 108, along with the processing acts associated therewith, are not employed upstream of the cell disruption apparatus 104). The ground, wet cannabis material 114 (or the partially dewatered cannabis material 116; or the wetted cannabis material 118) may, for example, comprise greater than or equal to about twenty-five (25) percent of the water present, at the time of harvesting, within the harvested portions of one or more cannabis plants employed to form the ground, wet cannabis material 114.

If employed, the vacuum distillation process facilitated by the cell disruption apparatus 104 may include subjecting the wet cannabis particles to increasingly negative pressures to rupture the cell walls of the plant cells of the wet cannabis particles and boil off different chemical compounds of the wet cannabis particles at different times. The vacuum distillation process may, for example, gradually increase negative pressures applied to the wet cannabis particles up to about 10⁻³ pounds per square inch absolute (psia). In some embodiments, the vacuum distillation process subjects the wet cannabis particles to increasingly negative pressures within a range of from about −4 psig to about 10⁻³ psia (e.g., from about −2 psig to about 10⁻³ psia). The different chemical compounds of the wet cannabis particles may be boiled off and separated from one another based on their relative volatilities, with relatively more volatile chemical compounds being boiled off earlier and at relatively lower negative pressures, and relatively less volatile chemical compounds being boiled off later and at relatively higher negative pressures. By way of non-limiting example, terpenes, esters, and water of the wet cannabis particles may be boiled off (e.g., sequentially, simultaneously, a combination thereof) at one or more negative pressures, and then one or more cannabinoids (e.g., CBD, THC, CBA, CBG, CBH) of the wet cannabis particles may be boiled off (e.g., sequentially, simultaneously, a combination thereof) at one or more relatively greater negative pressures. In some embodiments, terpenes and esters of the wet cannabis particles are boiled off at one or more relatively lower negative pressures, followed by water of the wet cannabis particles at a relatively higher negative pressure, followed by CBD of the wet cannabis particles at a relatively higher negative pressure, followed by one or more (e.g., each) of THC, CBA, CBG, and CBH of the wet cannabis particles at one or more relatively higher negative pressures. Optionally, the wet cannabis particles may be heated to assist with boiling off one or more chemical compounds of the wet cannabis particles, such as one or more chemical compounds having relatively lower volatilities. By way of non-limiting example, the wet cannabis particles may be heated to a temperature within a range of from about 25° C. to about 75° C., such as from about 35° C. to about 65° C., or from about 40° C. to about 60° C.

Although the cannabis processing system 100 is depicted as including a single (e.g., only one) cell disruption apparatus 104 in FIG. 1, the cannabis processing system 100 may include any number of cell disruption apparatuses 104. Put another way, the cannabis processing system 100 may include a single (e.g., only one) cell disruption apparatus 104, or may include multiple (e.g., more than one) cell disruption apparatuses 104. If the cannabis processing system 100 includes multiple cell disruption apparatuses 104, each of the cell disruption apparatuses 104 may be substantially the same (e.g., exhibit substantially the same components, component sizes, component shapes, component material compositions, component material distributions, component positions, component orientations, etc.) and may be operated under substantially the same conditions, or at least one of the cell disruption apparatuses 104 may be different (e.g., exhibit one or more of different components, different component sizes, different component shapes, different component material compositions, different component material distributions, different component positions, different component orientations, etc.) than at least one other of the cell disruption apparatuses 104 and/or may be operated under different conditions than at least one other of the cell disruption apparatuses 104. In some embodiments, two of more cell disruption apparatuses 104 are provided in parallel with one another. In additional embodiments, two of more cell disruption apparatuses 104 are provided in series with one another.

With continued reference to FIG. 1, if present, the separation apparatus 110 may comprise at least one apparatus configured and operated to separate one or more components of the cellularly-disrupted cannabis effluent 120 exiting the cell disruption apparatus 104 from one another. By way of non-limiting example, if present, the separation apparatus 110 may be configured and operated to separate (e.g., extract) one or more desirable cannabinoids of the cellularly-disrupted cannabis effluent 120 from one or more other chemical compounds of the cellularly-disrupted cannabis effluent 120 (e.g., one or more non-cannabinoid compounds, one or more undesirables cannabinoids). The configuration and use of the separation apparatus 110, if any, may at least partially dependent on the configuration and use of the cell disruption apparatus 104.

In some embodiments, such as some embodiments wherein the cell disruption apparatus 104 is configured and operated to flash freeze or apply negative pressure to the wet cannabis particles produced by the grinding apparatus 102, the separation apparatus 110 is at least one extraction apparatus configured and operated to receive and combine (e.g., mix) the cellularly-disrupted cannabis effluent 120 with at least one cannabinoid extraction solvent to dissolve one or more desirable cannabinoids of the cellularly-disrupted cannabis effluent 120 and form a cannabinoid solution. The cannabinoid solution may then be removed from other components of the cellularly-disrupted cannabis effluent 120 (e.g., in at least one other separation apparatus 110, such as a filtration apparatus), and the cannabinoid extraction solvent thereof may be driven off (e.g., in at least one additional separation apparatus 110, such one or more of an evaporation apparatus and a distillation apparatus), leaving the one or more desirable cannabinoids.

In additional embodiments, such as some embodiments wherein the cell disruption apparatus 104 is configured and operated to interact the wet cannabis particles produced by the grinding apparatus 102 with at least one cellulose solvent, the cellulose solvent and dissolved cellulose of the cellularly-disrupted cannabis effluent 120 is separated from the other components of the cellularly-disrupted cannabis effluent 120 using at least one separation apparatus 110. The separation apparatus 110 may, for example, employ one or more of heat distillation, temperature-based separation (e.g., winterization), and vacuum distillation to separate the cellulose solvent and dissolved cellulose of the cellularly-disrupted cannabis effluent 120 from the other components of the cellularly-disrupted cannabis effluent 120. Thereafter, one or more remaining, desirable cannabinoids of the cellularly-disrupted cannabis effluent 120 may be separated from other, remaining components of the cellularly-disrupted cannabis effluent 120 in the manner previously described (e.g., using one or more additional separation apparatuses 110, such as an extractor apparatus, a filtration apparatus, and an evaporation apparatus).

In further embodiments, such as some embodiments wherein the cell disruption apparatus 104 is configured and operated to subject the wet cannabis particles produced by the grinding apparatus 102 to vacuum distillation, one or more desirable cannabinoids exiting the cell disruption apparatus 104 are already sufficiently separated from other chemical compounds exiting the cell disruption apparatus 104 (e.g., at different times than the desirable cannabinoid(s)), and the separation apparatus 110 is omitted. In additional embodiments, the separation apparatus 110 may employ vacuum distillation to separate desirable cannabinoids from cannabis particles. In some such embodiment, the separation apparatus 110 is without previously disrupting the cannabis particles using a separate cell disruption apparatus 104. As a non-limiting example, the separation apparatus 110 may be employed to separate one or more desirable cannabinoids within the cannabis particles (e.g., wet cannabis particles and/or dry cannabis particles) without previously treating the cannabis particles using a separate cell disruption apparatus 104.

The cannabis processing system 100 may include any number of separation apparatus 110 downstream of the cell disruption apparatus 104, such as a single (e.g., only one) separation apparatus 110, multiple (e.g., more than one) separation apparatus 110, or no separation apparatus 110. If the cannabis processing system 100 includes multiple separation apparatuses 110 downstream of the cell disruption apparatus 104, each of the wetting apparatuses 108 may be substantially the same and may be operated under substantially the same conditions, or at least one of the multiple separation apparatuses 110 may be different than at least one other of the separation apparatuses 110 and/or may be operated under different conditions than at least one other of the separation apparatuses 110. In some embodiments, two of more multiple separation apparatuses 110 are provided in parallel with one another. In additional embodiments, two of more multiple separation apparatuses 110 are provided in series with one another.

The systems and methods of the disclosure may provide enhanced efficiency, reduced costs, and increase yield as compared to conventional cannabis processing systems and methods. For example, the systems (e.g., the cannabis processing system 100) and methods of the disclosure facilitate the simple processing of wet cannabis cuttings to remove desirable cannabinoids therefrom, saving significant time, labor, and expense as compared to conventional systems and methods of processing cannabis that require drying out wet cannabis cuttings prior to further processing thereof. In addition, the systems and methods of the disclosure may facilitate increased cannabinoid product yield compared to conventional systems and methods of processing wet cannabis cuttings, and may facilitate cannabinoid product yields at least as good as (or better than) those facilitated by conventional systems and methods of processing dried cannabis cuttings.

The following examples serve to explain embodiments of the disclosure in more detail. These examples are not to be construed as being exhaustive, exclusive, or otherwise limiting as to the scope of the disclosure.

EXAMPLES Example 1: Plant Cell Damage from Breakdown of Wet Cannabis Cuttings

Cannabis plant cell damage effectuated by the mechanical breakdown of wet cannabis cuttings was analyzed. The analysis investigated the number of plant cells damaged as a function of the particle size of the discrete wet cannabis particles resulting from mechanical breakdown of cannabis plant leaves and stems. FIG. 2 is a graphical representation of the results of the analysis. As shown in FIG. 2, the fraction of total cannabis plant cells that are damaged and release their contents decreases as the size of the discrete wet cannabis particles increases.

Example 2: Water Released from Breakdown of Wet Cannabis Cuttings

The amount of water released from wet cannabis cuttings as a result of the mechanical breakdown of the wet cannabis cuttings was analyzed. The analysis investigated the volume fraction of liquid (liquid volume/total volume) present after mechanical breakdown of wet cannabis cuttings having different amounts of initial water to discrete wet cannabis particles having different particle sizes. FIG. 3 is a graphical representation of the results of the analysis. As shown in FIG. 3, the volume fraction of liquid decreases as wet cannabis particle size increases, but is also dependent upon the initial volume fraction water present in the wet cannabis cuttings. The initial wetness of the wet cannabis cuttings dominates the volume fraction liquid as cutting the wet cannabis cuttings releases very little liquid, as is observed with the 0% water curve in FIG. 3.

Example 3: Ethanol as Cooling Media for Flash Freezing

The use of ethanol as a cooling media for the disruption of cell walls of plant cells of ground, wet cannabis material by way of flash freezing was analyzed. Flash freezing was modeled using an energy balance, a water and ethanol azeotrope cooling media (“solvent”), the heat capacity of the ground, wet cannabis material, and the heat of fusion of water. The solvent was assumed to enter the flash freezing apparatus at −70° C., and to exit the flash freezing apparatus at the freezing temperature of the cannabis plant (a temperature less than or equal to 0° C., depending on the cannabis plant strain).

FIG. 4 is a graphical representation showing the weight of solvent per 100 kilograms (kg) of ground, wet cannabis material (having 10% excess water content) needed to freeze cannabis plant cells of the ground, wet cannabis material as a function of freezing temperature following mixing of the solvent and the ground, wet cannabis material, as well as the estimated fraction (%) of CBD in solvent mixture after filtration of the resulting cellularly-disrupted cannabis effluent. The analysis assumes 1% CBD in the ground, wet cannabis material, and that all of the CBD is present in the solvent mixture after filtration.

FIG. 5 is a graphical representation showing the weight of ethanol (“solvent”) per 100 kg of ground, wet cannabis material (having 10 percent excess water content) needed to freeze cannabis plant cells of the ground, wet cannabis material as a function of flash freezing temperature following mixing of the ethanol and ground, wet cannabis material, as well as the estimated fractions (%) of ethanol and water in solvent mixture after filtration of the resulting cellularly-disrupted cannabis effluent.

Example 4: Cannabinoid Separation

A cannabinoid separation subsystem for use as the at least one separation apparatus 110 (FIG. 1) was modeled and analyzed for conditions wherein the cell disruption apparatus 104 (FIG. 1) comprises a flash freezing apparatus, a cannabinoid extraction solvent is employed as a cooling media for the flash freezing process (in addition to being utilized for cannabinoid extraction following the flash freezing process), and the cannabinoid extraction solvent is recovered and recycled to the flash freezing apparatus following separation of desired cannabinoids therefrom.

FIG. 6 is a simplified schematic view of the cannabinoid separation subsystem in use and operation. As shown in FIG. 6, the cannabinoid separation subsystem includes a filter 202, a first heat exchanger 204, a distillation column 206, a second heat exchanger 208, a third heat exchanger 210, and a decanter 212. The filter 202 is downstream of the downstream of the cell disruption apparatus 104 and is figured to separate a solution of the cannabinoid extraction solvent and one or more cannabinoids from other components (e.g., waste) of the cellularly-disrupted cannabis effluent (e.g., the cellularly-disrupted cannabis effluent 120 (FIG. 1)) exiting the cell disruption apparatus 104. The first heat exchanger 204 is downstream of the filter 202, and is configured and operated to receive a first stream S9 from the filter and to produce a second stream S14. The distillation column 206 is downstream of the first heat exchanger 204 and is configured to receive the first stream S9 and produce a third stream S12 and a fourth stream S13. The third stream S12 includes the cannabinoid extraction solvent and is directed to and received by the second heat exchanger 208 to produce a fifth stream S19, which is then recycled back to the cell disruption apparatus 104. The fourth stream S13 includes water and cannabinoids and is directed to and received by the third heat exchanger 210 to produce a sixth stream S18. The sixth stream S18 is directed to and received by the decanter 212 to produce a seventh stream S15 and an eighth stream S16. The seventh stream S15 includes a relatively higher amount (e.g., mass fraction) of water and a relatively lower amount of cannabinoids, and the eighth stream S16 includes a relatively higher amount (e.g., mass fraction) of cannabinoids and a relatively lower amount of water.

FIGS. 7A through 9B are tables showing the properties (e.g., compositions, temperatures, pressures, densities, flowrates) of the streams S9, S12, S13, S14, S15, S16, S18, and S19 of the cannabinoid separation subsystem shown in FIG. 6 using different cannabinoid extraction solvents. FIGS. 7A and 7B show the properties of the streams S9, S12, S13, S14, S15, S16, S18, and S19 using ethanol as the cannabinoid extraction solvent. FIGS. 8A and 8B show the properties of the streams S9, S12, S13, S14, S15, S16, S18, and S19 using isopropanol as the cannabinoid extraction solvent. FIGS. 9A and 9B show the properties of the streams S9, S12, S13, S14, S15, S16, S18, and S19 using n-butanol as the cannabinoid extraction solvent.
